Copy These Lines Into Your RFQ
EN ISO 14122-4 Procurement Checklist — the Seven Lines That Matter
European tenders reward precision and punish paraphrase. When your RFQ states the seven lines below verbatim, every bidder prices the same ladder — and the DoC that arrives months later can be checked line against line against what you ordered.
| RFQ Line | The Clause Behind It | Our Standard Answer |
|---|---|---|
| "Rung spacing 225–300 mm, single-bar rungs of at least 22 mm" | the geometry rule every tape check starts from | 280 mm spacing standard; rung section up-sized to the 22 mm minimum where your spec enforces it |
| "Climbing width 400–600 mm between rails" | the width band that fits a climber with equipment | 500 mm clear width — mid-band by design |
| "Safety cage above 3 m of climb" | the trigger that turns a ladder into a caged ladder | cage from 2.2 m, Φ700 mm, hoops 40×5 mm at 1500 mm centres |
| "No single flight over 6 m; rest platforms at the breaks" | the flight cap that structures every tall climb | flight layout on the GA drawing at quote stage, platforms in the same kit |
| "Ladder safety system provided above 10 m total climb" | the threshold where the system becomes mandatory alongside the cage | LSS-ready stringer fabricated with the cage intact — system scope named in the quote |
| "Hoop spacing not exceeding 1500 mm" | the cage band that keeps a falling climber inside | hoops at the 1500 mm maximum permitted, vertical straps 30×3 mm between |
| "DoC to EN ISO 14122-4:2016 plus MTC 3.1" | the documentation half of conformity | both in the crate, plus structural calcs and trial-assembly photos |
Seven lines, one page — forward them as-is, or send us your existing RFQ and we mark the gaps against this checklist free.
Cage Alone, or Cage Plus System?
EN ISO Path Selection — New, Existing and In-Between
Under 14122-4 the cage is not an alternative to a system — above 10 m they coexist, and below 3 m neither is asked for. The rows below cover the situations European buyers actually sit in, including the awkward ones: inherited ladders, relocations and machinery access.
| Your Situation | The Rule That Decides | Our Supply |
|---|---|---|
| New build, climb under 3 m | cage not triggered; geometry bands still govern | uncaged ladder, 280 mm rungs, 500 mm width, DoC to 14122-4 |
| New build, 3 to 10 m | cage mandatory, flights capped at 6 m, system not yet required | caged multi-flight build with platforms at the breaks |
| New build, over 10 m | ladder safety system mandatory alongside the cage | caged, LSS-ready package — system integrator scope coordinated in writing |
| Inherited ladder at 12 m, cage only, no system | the asset predates the threshold logic — the gap is the system, not the cage | LSS-ready conversion kit path quoted against the existing stringers |
| Ladder moving between EU sites | the destination inspection applies the current edition, not the origin's memory | gap analysis against 14122-4:2016 before relocation, documented |
| Machinery access, not building access | 14122 governs machine-mounted access as machinery part four of the series | machine-mounted caged builds with saddle brackets to your frame geometry |
Climb height plus situation — two facts, and the third column becomes your purchase order, quoted inside 24 hours.
Feature — Advantage — Your Outcome
EN ISO 14122-4 Features That Answer an Audit
Five features, each mapped to a 14122-4 check a notified reviewer or client auditor might run.
| Feature | Advantage | Your Outcome |
|---|---|---|
| Rungs at 280 mm, 22 mm option | mid-band spacing with the single-bar minimum available | geometry row of any audit closes on sight |
| Cage from 2.2 m, hoops at 1500 mm | cage starts before the 3 m trigger, hoops at the 1500 mm maximum permitted | trigger check passes with margin, hoop check holds the permitted maximum |
| Flights engineered to 6 m breaks | flight cap and platform rule designed in | tall climbs pass without a platform count argument |
| DoC naming EN ISO 14122-4:2016 | edition-precise conformity statement | document review ends at the first page |
| LSS-ready stringer above 10 m | system mounting without ladder rework | the 10 m threshold costs a rail kit, not a rebuild |

Deep Dive — The 3 / 6 / 10 m Decision Ladder
How EN ISO 14122-4 Decides What Your Ladder Needs
EN ISO 14122-4:2016 reads like a decision tree built on three numbers. Start at 3 m: once the climb exceeds 3 m, a safety cage enters the design. Move to 6 m: no single flight may run longer than 6 m, so taller climbs are broken by rest platforms rather than climbed in one push. Arrive at 10 m: a ladder safety system becomes mandatory, and it works alongside the cage rather than replacing it.
Around those thresholds sit the geometry rules that make the ladder itself compliant — rung spacing between 225 and 300 mm, a climbing width of 400 to 600 mm between the rails, single-bar rungs of at least 22 mm, and cage hoops spaced no more than 1500 mm apart. Our standard build — Φ20 rungs at 280 mm, 500 mm width, hoops 40×5 at 1500 mm — lands mid-band on every row, with up-sizing available where a client enforces the 22 mm rung minimum.
Walk the table top to bottom and every requirement for your climb height is on one screen.
| Your Climb Height | What the Standard Requires | How We Build It |
|---|---|---|
| Up to 3 m | Cage not yet triggered; geometry rules still apply | Standard rung and width geometry; cage optional per spec |
| Over 3 m | Safety cage required for the climb | Φ700 cage, hoops 40×5 at 1500 mm centres |
| Flights over 6 m | Rest platforms break the climb — no single flight over 6 m | Platform positions fixed on the GA drawing before quote |
| Above 10 m | Ladder safety system required; cage remains | Ladder fabricated LSS-ready with the cage intact |
| Any height | Rung spacing 225–300 mm; width 400–600 mm; single-bar rungs ≥ 22 mm | 280 mm spacing and 500 mm width standard; rung size per spec sheet |
| Documentation | Conformity shown through the documented DoC file | DoC naming EN ISO 14122-4:2016 plus MTC 3.1 with every order |
Why 6 m Flights Matter
The platform rule quietly improves rescue, fatigue and inspection outcomes — and satisfies landing rules in other regimes, from Singapore WSH to tender clauses citing multiple standards.
